Jeff MacMillan (born March 30, 1979 in Durham, Ontario) is a retired Canadian professional ice hockey player. MacMillan began his career in 1996, icing for the junior team the Oshawa Generals in the OHL. MacMillan stayed with the Generals for three years, making almost 170 appearances in that time. His solid defensive play combined with a reasonable offensive output for a defenceman meant that in the 1999 NHL entry draft, MacMillan was drafted in the seventh round by the Dallas Stars.
